SPECIFICATION forming part of Letters Patent No. 658,560, dated September 25, 1900. Application filed January 10,1898. b'erial No. 666,261. \No model.)

To all whom it ntcty concern:

Be it known that I, ZALMON G. SHOLES, a resident of Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Type-WVriting Machines, of which I do declare the following to be a full, clear, and exact description, sufiieient to enable others skilled in the art to make and use the same.

The present invention has relation more particularly to that class of type-writing machines commonly known as pad-machines, in which provision is made for inking the type by means of an ink-pad, as distinguished from the class of machines in which inkingribbons are employed. The invention relates also particularly to that class of machines in which the printing-type are carried upon the ends of type-bars that are operated by suitable lever mechanism of the keyboard of the machine.

One object of this invention is to provide improved mechanism whereby the type as they travel from the ink-pad to the platen will be partially revolved, so that the face of the type will bear upon the ink-pad when at rest and will be so revolved as to be presented squarely to the platen when the type-bars are swung through the medium of the key-lever mechanism and whereby undue revolution of the type-bar is prevented and the type are alincd by a fixed guide arranged at the printlug-point.

A further object of this invention is to provide a suitable curved or annular support. or.

holder for the ink-pad and means for stifiening the pad and means for feeding the pad into and out of its holder.

The invention consists in the features of construct-ion hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the claims at the end of this specification.

A designates the frame of the machine, around the top opening or well of which the type bars B are hung in circular series. Each of the typebars B is provided at its end with two type b b, as in the familiar Remington Standard machines. The inner end of each of the type-bars B is reduced, as at b and of cylindrical outline and is pivotally held within a swinging box or support C, as clearly shown in Fig. 6 of the drawings. Each of the swinging boxes or supports 0 is formed with an open space 0 to admit a bevelpinion D, that'is fixed to the reduced portion b of the type-bar B. Each box or support 0 is formed with trunnions o, adapted to fit into trunnion-seats e of the corresponding hanger E. The part0 may therefore be termed a pivoted yoke or bearing-box for swinging the type-bar B to the printing-point and permitting it to revolve at the same time, and it is provided also with a tailpiece 0 having the usual eye 0 for attachment to the rod, that is suitably joined to the corresponding keylever F. The hangersE are of theconstruction shown more particularly in Figs. 3, 4., and 5 of the drawings, and these hangers are mounted upon the top of the hanger-ring G, to which they are adjust-ably connected by screws g, that pass into the hanger-ring and through the cap-plates g. Each of the hangers E has its rear portion of yoke shape and connected by a tie-rod e or screw-bolt, and one side of the yoke-shaped hanger is extended inwardly and curved downwardly, as at 6 to form a guide for the type-bars. The bodies of the type-bars B are flattened, as shown, so that as the bars are swung upward the fiat side of the bars will bear against the guide-plates c and thus aid in securing the square delivery of the type against the platen. The extreme lower end of each guide e is bent outwardly, so as to insure the passage of the corresponding type-bar along the side of the guide. Each of the hangersE is provided with a depending plate 6 the inner face of which is formed. with a curved rack-bar 6 comprising a series of laterally-projecting teeth which are adapted to engage with the bevel-pinion D, that is fixed to the corresponding type-bar B.

Across the central opening of the top plate of the machine extends abar H, thatis united, as by screws h, to the top plate, and'this bar H is formed with two guide-holes h and h to receive the corresponding type b and b of the type-bar. That part 72, of the bar H that extends between the holes h and 71. has its under portion formed with bevel-faces, as clearly seen in Fig. 2, in order to more accurately center or aline the type with respect to the platen as the type are swung to the printingpoint. By reference to Fig. 1 it will be seen that the holes h and h are oblong, since it is only necessary that two sides of the holes should act in guiding the type, the guiding of the typein opposite direction being effected by the part 71. In order to reduce as far as possible the width of the bar H without weak-' ening the same, I prefer to arrange the holes h and lfidiagonally across the bar, as clearly seen in Fig. 1.

At a distance below the top of the main frame A is located a holder N for an annular ink-pad M, that is held in position by suitable supports m and at such point that the pad will serve as a bearing for the type when the type-bar is at rest.

From the foregoing construction it will be seen that when the type-bars are in normal position all the type will rest against the face of the annular ink-pad M and will receive ink therefrom. It, now, one of the key-levers F be depressed, the corresponding type-bar and upon either side of the beveled cross-bar h The types 'will thus be accurately directed at the final end of their upward movement, thereby securing an accurate alinement of the printing. As is well known, in the Remington machine a cylindrical platen is arranged transversely of the machine to receive the impact of the types and in the normal position of the platen only one of the two types on a bar can strike. When the platen is shifted rearwardly, only the other of said types can strike. When pressure upon the key-lever F is released, the type-bar B will be retracted in the usual manner, and as the type-bar B moves downward the passage of the beveled pinion D along the rackbar 6 will effect a half-revolution of the typebar and types, thereby causing the types to bear against the face of the ink-pad M. By forming the rack-bar 6 upon the inner face of the depending portion 6 of each of the hangers E these rack-bars can be stamped with great accuracy and but slight cost from the plates.

In order to facilitate the introduction of the ink-pad M into its annular holder N, I prefer to employ the mechanism hereinafter described and to construct the holder as hereinafter set forth. The body of the holder N is preferably of sheet metal, and its upper and lower edges are shaped to receive and retain in place the ink-pad M. In the outer face of the holder N is formed an opening'n, through which theink-pad will be inserted, and in the top edge of the holder above the opening it is formed a slot at, the purpose of which will presently appear. The openings 1?. and it may be closed by a sliding cover N, preferably formed of sheet metal, the upper and lower edges of which are bent to overlap the top and bottom of the holder N, as shown. At one side of the opening at there is a raised stop or offset 72 to limit the movement of the slide-cover N, and at the rear edge of the slide-cover a notch 11 may be formed to permit the easy shifting of the cover. The purpose of the long slot n of the holder N and the slot 01 of the cover N is to admit the teeth of a spur-wheel P, that is carried upon the end of the shaft 19, revolubly mounted at the upper end of a bracket R, the outer end of the shaft 0 having fixed thereto a crank 19, whereby the shaft and wheel may be turned. The lower end of the bracket R is attached to one of the side bars of the main lower edge of the strip S will also be formed of teeth 3, that will be slightly embedded in the lower edge of the pad M, and thus more securely retain the pad upon the strip S. The

IIO

cutting away of the edges of the strip S permits the strip to be more readily bent, so as to fit within the annular pad-holder. After the strip S has been attached to the pad M in manner last described one end of the pad and strip will be placed Within the opening 12 of the holder N, so that the teeth 3 of the strip S will be engaged by the spur-wheel P, after which by turning the crank 19 the spur wheel P will cause the strip S and pad M to pass completely into the holder N.

It is obvious that in attempting to insert a pad into the holder Nfrom theinside it would be necessary either to remove the type-bars from the machine or to adopt some means for temporarily bunching together the type ends thereof about centrallyof the machine,which would batter the types and perhaps bend some of the type-bars. By the described construction the pad is quickly inserted from the outside without removing the type-bars or bunching them. A distinct and further advantage is gained byinserting the pad endwise in to the annular or curved holder, as the end of the pad can be readily threaded or passed between the usual type-bar con nections or other parts of the machine and inserted into the holder, and the pad can then be readily fed around either in the described manner or otherwise. The cover N affords a support for that portion of the yielding pad which remains opposite the opening 02 made for its insertion.

It is obvious that certain features of the inven tion may be employed without the others.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is 1 1.
